If I try:
url = "https://www.economist.com/news/finance-and-economics/21727073-economists-struggle-work-out-how-much-free-economy-comes-cost"
{:ok, %HTTPoison.Response{status_code: 200, body: body}} = HTTPoison.get(url)
IO.binwrite body
I see garbled text (instead of html) in the console. But if I view source on the webpage, I see html there. What am I doing wrong?
PS: it works fine with a js http client (axios.js), not sure why it doesn't work with httpoison
That URL returns the body in gzipped form and indicates this by sending the header Content-Encoding: gzip. hackney, the library HTTPoison is built on, does not automatically decode this. This feature will likely be added at some point. Until then, you can decode the body yourself using the :zlib module if the Content-Encoding is gzip:
url = "https://www.economist.com/news/finance-and-economics/21727073-economists-struggle-work-out-how-much-free-economy-comes-cost"
{:ok, %HTTPoison.Response{status_code: 200, headers: headers, body: body}} = HTTPoison.get(url)
gzip? = Enum.any?(headers, fn {name, value} ->
# Headers are case-insensitive so we compare their lower case form.
:hackney_bstr.to_lower(name) == "content-encoding" &&
:hackney_bstr.to_lower(value) == "gzip"
end)
body = if gzip?, do: :zlib.gunzip(body), else: body
IO.write body

I'm still relatively new to Python and my first time to use aiohttp so I'm hoping someone can help spot where my problem is.
I have a function that does the following:
retrieves from the JSON payload two base64 strings - base64Front and base64Back
decode them, save to "images" folder
send the Front.jpg and Back.jpg to an external API
this external API expects a multipart/form-data
imgDataF = base64.b64decode(base64FrontStr)
frontFilename = 'images/Front.jpg'
with open(frontFilename, 'wb') as frontImgFile:
frontImgFile.write(imgDataF)
imgDataB = base64.b64decode(base64BackStr)
backFilename = 'images/Back.jpg'
with open(backFilename, 'wb') as backImgFile:
backImgFile.write(imgDataB)
headers = {
'Content-Type': 'multipart/form-data',
'AccountAccessKey': 'some-access-key',
'SecretToken': 'some-secret-token'
}
url = 'https://external-api/2.0/AuthenticateDoc'
files = [('file', open('./images/Front.jpg', 'rb')),
('file', open('./images/Back.jpg', 'rb'))]
async with aiohttp.ClientSession() as session:
async with session.post(url, data=files, headers=headers) as resp:
print(resp.status)
print(await resp .json())
The response I'm getting is status code 400 with:
{'ErrorCode': 1040, 'ErrorMessage': 'Malformed/Invalid Request detected'}
If I call the url via Postman and send the two jpg files, I get status code 200.
Hope someone can help here.
Thanks in advance.
Try using FormData to construct your request. Remove the content type from header and use it in FormData field as below:
data = FormData()
data.add_field('file',
open('Front.jpg', 'rb'),
filename='Front.jpg',
content_type='multipart/form-data')
await session.post(url, data=data)
Reference: https://docs.aiohttp.org/en/stable/client_quickstart.html#post-a-multipart-encoded-file
I've been using the code below to call a third party API . This code works fine (i've changed the url and the credentials but the structure of the code is the same) :
require 'base64'
require 'httparty'
require 'json'
######################################################################
# Get the token first
######################################################################
consumer_key = "my_key"
consumer_secret = "my_secret"
credentials = Base64.encode64("#{consumer_key}:#{consumer_secret}").gsub("\n", '')
url = "https://mysite/token"
body = "grant_type=client_credentials"
headers = {
"Authorization" => "Basic #{credentials}",
"Content-Type" => "application/x-www-form-urlencoded;charset=UTF-8"
}
r = HTTParty.post(url, body: body, headers: headers)
bearer_token = JSON.parse(r.body)['access_token']
######################################################################
# Use the token in a call as authorisation header
######################################################################
api_url = "https://apisite/the_value_i_am_looking_for_in_the_api"
url = URI.parse(api_url)
req = Net::HTTP.new(url.host, url.port)
req.use_ssl = true
# If we are just passing a key that doesn't need to be in the token format
headers = {
'Authorization' => "Bearer #{bearer_token}"
}
# Get the response back (he data is in the response body: resp.body )
resp = req.get(url, headers)
My issue is that the API providers have changed their API so you now need to pass an "accept" into the call via the header. I used POSTMAN to make the call, added the accept to the header and was able to get it working without issue. So far so good.
I then changed my ruby code to extend the headers section to include the accept, using the code below:
headers = {
'Authorization' => "Bearer #{bearer_token}",
'Accept' => 'application/vnd.bluebadge-api.v1+json'
}
I've not added an accept to a header before so I may have gotten the syntax wrong.
However, this returns an unauthorised 401 response code:
#<Net::HTTPUnauthorized 401 Unauthorized readbody=true>
I thought I might have the credentials wrong so remove the accept, try again and this changes to a 406 response code:
#<Net::HTTPNotAcceptable 406 Not Acceptable readbody=true>
If I examine the response I get the message I would expect that the accept header is not the supported version. So I know the credentials are correct (and the fact they match the postman credentials which works):
"{\"apiVersion\": \"1\",\"context\": null,\"id\": null,\"method\": null,\"error\": {\"code\": null,\"message\": null,\"reason\": \"Accept header version is not a currently supported version.\",\"errors\": null}}\n"
So I know all my credentials are correct because I've copied them into the postman request which works with no errors. The value for the accept header is correct because I copied that from a working postman request too.
I am at a loss for why this wouldn't work.
I've looked through the NET HTTP library and cant find anything to help me there. I've seen a couple of posts elsewhere which I've tried and they haven't worked either.
I appreciate any help in trying to solve this.
Found the problem. I was using the credentials from the production environment to get the token then trying to query the test environment API. In my defence they look very similar (only 3 characters different). I think I had a case of the code blindness.
The code I posted does work when I put the correct URL for the environments.
I also found that I could use this:
uri = URI.parse("https://myapi/some_text")
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
request = Net::HTTP::Get.new(uri.request_uri)
request["Authorization"] = "Bearer #{bearer_token}"
request["Accept"] = "application/vnd.bluebadge-api.v1+json"
response = http.request(request)
Or using HTTParty like this:
response = HTTParty.get('https://myapi/some_text', {
headers: {"Authorization" => "Bearer #{bearer_token}", "Accept" => "application/vnd.bluebadge-api.v1+json" }
})
I would prefer the format of my orginal code or the HTTparty code because it is easy to see from the code that you're passing headers. Hopefully this will help others to double check their authorization credentials...
I call the google.webmasters.api via Power-Query(M) and managed to configure the oath2 and made my first successfull call to get & list.
Now i try to call the /searchAnalytics/query? which is working only with Post.
This always responds in a 400 error. Formating of the Query or the Url is not working correctly.

Any Ideas whats wrong?
Thx
Ensure request headers are valid. Server expects Content-Type header, not ContentType.
The documentation (https://developers.google.com/webmaster-tools/search-console-api-original/v3/searchanalytics/query#try-it) suggest requests should be something like:
POST https://www.googleapis.com/webmasters/v3/sites/[SITEURL]/searchAnalytics/query HTTP/1.1
Authorization: Bearer [YOUR_ACCESS_TOKEN]
Accept: application/json
Content-Type: application/json
{}
So seems like main takeaways are:
HTTP POST method must be used
Web.Contents documentation (https://learn.microsoft.com/en-us/powerquery-m/web-contents) suggests including the Content field in the options record to change request from GET to POST.
URL must be valid
You haven't provided your actual URL, so you'll have to validate it for yourself. I would get rid of the trailing ? in your url (as you aren't including a query string -- and even if you were, you should pass them to the Query field of the options record instead of building the query string yourself).
Headers (Authorization, Accept, Content-Type) should be valid/present.
Build your headers in a separation expression. Then pass that expression to the Headers field of the options record. This gives you the chance to review/inspect your headers (to ensure they are as intended).
Body should contain valid JSON to pass to the API method.
Creating valid JSON via manual string concatenation is liable to error. Using Json.FromValue (https://learn.microsoft.com/en-us/powerquery-m/json-fromvalue) seems a better approach.
All in all, your M code might look something like:
let
// Some other code is needed here, in which you define the expression api_token
AccessTokenList = List.Buffer(api_token),
access_token = AccessTokenList{0},
AuthKey = "Bearer " & access_token,
requestHeaders = [Authorization = AuthKey, #"Content-Type" = "application/json", Accept = "application/json"],
parametersToPost = [startDate = "2019-01-01", endDate = "2019-02-02"], // Can include other parameters here e.g. dimensions, as mentioned in Search Console API documentaton.
jsonToPost = Json.FromValue(parametersToPost, TextEncoding.Utf8), // Second argument not required (as is default), but just be explicit until you've got everything working.
url = "https://www.googleapis.com/webmasters/v3/sites/https%3A%2F%2Fxxxxxxxxx.xxx/searchAnalytics/query", // Uri.EscapeDataString function can be use for URL encoding
response = Web.Contents(url, [Headers=requestHeaders, Content=jsonToPost])

Few questions:
Does facebook source parameter accept base64 encoded image data?
Has anyone tried using the source parameter in the graph api explorer and have a working sample?
should the source param value should be url-encoded?
Note: My access token has all the required permissions and if i am not wrong, my encoding seems to be wrong. The base64 encoded text above is a complete image and i could decode it and get the image.
Ok. This is going to sound crazy. After a week of trying I was able to post an image successfully to the facebook wall. The fix was to send the raw binary data as it is (no base64 encoding - fb does not like it) and make sure your multipart/form-data is correct. For instance, if you boundary is defined as "boundary=--xxxsrixxx" your actual request should look like this "----xxxsrixxx\r\nContent-Disposition......\r\n----xxxsrixxx"
This works fine for me, it only uses native JavaScript features and a file input:
const fileReader = new FileReader();
const file = document.getElementById('imageInput').files[0];
fileReader.onloadend = async () => {
const photoData = new Blob([fileReader.result], {type: 'image/jpg'});
const formData = new FormData();
formData.append('access_token', pageAccessToken);
formData.append('source', photoData);
formData.append('message', 'some status message');
let response = await fetch(`https://graph.facebook.com/${pageId}/photos`, {
body: formData,
method: 'post'
});
response = await response.json();
console.log(response);
};
fileReader.readAsArrayBuffer(file);

I have a template like this:
<img class="picto"
ng-repeat="module in modules"
ng-src="{{module.Source}}"
title="{{module.Title}}"
ng-click="module.handler();"/>
When I set the $scope.modules array using static code, everything works fine, and the images are fetched via GET using media type "image/gif" (for gif files). However, when I retrieve the same array using $http.get() - see the code below -, angular tries to retrieve the images using media type "text/html" which results in an 404 error:
$http.get('/api/modules', {})
.success(function (data) {
$http.defaults.get = { 'Content-Type': 'image/gif' }; // apparently useless
$scope.modules = data;
for (var module in $scope.modules) {
$scope.modules[module].handler = function () { alert(this.Id); };
}
delete $http.defaults.get; // ...useless
});
Trying to add a header default did not help either (// apparently useless). Can you see what's wrong?
Try it with Accept: 'image/gif' instead of Content-Type: 'image/gif'.
The Content-Type header describes the data format you are sending to the server. The Accept header describes the data formats you accept in response from the server.
